Think of it this way-It's a funny song and Christine does perform it with an eerie similarity to the real Little Edie.
(it's disarming, really)
And, no doubt, there will be some explanation as to what's going on prior to her taking the stage. I think it may be a better sell than say, "Another Winter" which I adore, but I've seen the show many, many times and understand its context. Most of the Act II songs featuring Christine need to understand the context for.
This is possibly the one that requires the least explanation besides the House We Live In. (interesting idea, but not enough buildup of Christine's performance in the song, IMO.)
